Stopped: Slow/insufficient accrual
Background: Insomnia is associated with difficulty sleeping. The drug zolpidem is widely prescribed for insomnia. Women have reported worse effects from the drug than men. Women have higher amounts of zolpidem in their body that may persist after waking. Drug exposure may also depend on male hormones that change during prostate cancer therapy. Researchers want to see if these findings can provide a more-accurate dose to healthy women and men with prostate cancer. Objective: To study amounts of zolpidem in men who have been diagnosed with prostate cancer before they are castrated and after, and to compare these results to healthy women s. Eligibility: Men ages 18 and older who have been diagnosed with prostate cancer who are planning to receive androgen deprivation therapy (ADT) Healthy women age 18 and older Design: Participants will be screened with: Blood tests Physical exam Electrocardiogram (EKG) heart test Male participants will confirm their prostate cancer.
